Eryri bagpipes (plurale tantum)
electronic bagpipe by brand or trade-mark
According to MusicMoz, "The Eryri bagpipes take their name from the 'land of eagles', North Wales, UK; They are a hybrid design, taking ideas from the Irish, Scottish, Bulgarian and Hungarian pipes, which the maker researched whilst traveling in these countries".
MusicMoz also informs us that "They use a similar fingering to the Irish pipes and are based on the scale of D [major; ws], but will also play in C and G major and D, E and A minor".
